fix(parser): keep an indented list from being swallowed by a table

The parser rework dropped the list-awareness lookahead from preformatted's
entry patterns ('\n (?![\*\-])' became '\n '). In base mode this is masked
by sort order - listblock sorts before preformatted and wins the tie - but
table mode connects preformatted as a protected sub-mode without connecting
any list mode. Inside a table an indented list line therefore entered
preformatted instead of ending the table, and the table rewriter discarded the
resulting call: the list vanished from the output and the table's section-edit
range grew to cover it, so saving via the inline table editor overwrote the
list text.

Restore the lookahead. For DokuWiki syntax it is the original '(?![\*\-])'
(Listblock treats a bare * or - as a marker). For Markdown-preferred syntax the
guard follows GfmListblock, rejecting -, *, + and ordered markers only when
followed by whitespace or end of line, so mixed dw+md / md+dw wikis are fixed
too while an indented code block that merely starts with such a character (e.g.
a *** line) still parses as code.

Parsing: make parse syntax a per-parse value, drop ModeInterface

The active parse's syntax flavour is a per-parse question, not process-
global state: within a single request a plugin can render bundled
DokuWiki-syntax text inside an otherwise-Markdown page. Yet ModeRegistry
was a singleton that read $conf['syntax'] and the $PARSER_MODES global,
and every mode reached it through ModeRegistry::getInstance() — so the
flavour lived in shared mutable state that two parses in one request
would fight over.

Make the registry a short-lived value instead:

- ModeRegistry is constructed once per parse with an explicit $syntax
and injected into Parser, Handler and every mode. getSyntax() /
isDwPreferred() / isMdPreferred() consult $this->syntax; the
DOKU_UNITTEST-gated mode-list cache hack is gone (each registry is
fresh, nothing to invalidate).
- p_get_instructions() is now the single place in the pipeline where
$conf['syntax'] is read; from there the flavour travels as a
parameter. No code under inc/Parsing/ reads $conf['syntax'] directly
anymore — the five syntax-reading modes (Preformatted, GfmHr,
GfmEscape, Externallink, GfmQuote) route through $this->registry.

Keep the two concepts apart, as documented in the ModeRegistry and
AbstractMode docblocks: the user's configured *preference* stays in
$conf['syntax'] for UI code (toolbar, settings), while the active
parse's syntax is a parameter carried by the registry.

$PARSER_MODES is demoted to a deprecated, read-only mirror, published
during loadPluginModes() — third-party syntax plugins (columnlist,
alphalist2, phpwikify, skipentity) and the bundled info plugin read the
global directly, often from their constructors, so the taxonomy must
stay visible there. No core code reads the mirror.

Fold ModeInterface into AbstractMode while here: getSort()/handle() are
abstract, the connect callbacks carry defaults, and the public $Lexer
"FIXME should be done by setter" becomes setLexer()/getLexer() injected
by Parser::addMode() alongside the registry. Nested-content resolution
moves to the allowedCategories()/filterAllowedModes() hooks, resolved
once when the registry is attached.

Tests build their own parser/registry through ParserTestBase::setSyntax()
instead of mutating $conf and calling the removed ModeRegistry::reset().

Preformatted: leave boundary \n in stream when next line has content

Preformatted: leave boundary \n in stream when next line has content

Adds a zero-width lookahead exit (?=\n[^ \t\n]) ahead of the existing
consuming \n exit. When an indented code block is followed by a non-
blank line, the boundary newline now stays available for downstream
block-level matchers (GfmHr, GfmHeader, etc.) instead of being eaten
on the way out of preformatted mode.

Concretely fixes a thematic-break-after-indented-code case (GFM spec
case 85's trailing ----): without this change, GfmHr's \n anchor failed
because preformatted had already consumed the newline, and the bare
---- fell through to Entity which converted --- to an em-dash.

The consuming branch is kept as a fall-through for the blank-line and
end-of-input cases, where a pure lookahead would trip the lexer's
no-advance safety check.

Six PreformattedTest expectations updated: trailing cdata after a
preformatted block now carries the leading \n (rendered output is
unchanged — paragraph whitespace is trimmed).

remove getLineStartMarkers registry — sort order already wins

Preformatted's entry pattern carried a `(?![\*\-])` negative
lookahead to defer to list modes on indented bullet lines.
0cecf9d50 (2005, "new parser added") introduced it hardcoded;
7958e6980 (2026, "decouple hardcoded mode names in Eol and
Preformatted") refactored that hardcoded knowledge into
register/getLineStartMarkers on ModeRegistry so each list mode
owned its marker chars. Both preserved the behavior verbatim;
neither documented why it was needed.

Tracing the lexer, it isn't. ParallelRegex merges all entry
patterns into one PCRE expression; PCRE returns the leftmost
match and breaks ties on expression order. Modes are added in
sort order via ModeRegistry::getModes(), so Listblock (sort 10)
always precedes Preformatted (sort 20) and wins the tie on
" - foo" without any lookahead. The only test that caught a
difference was testPreformattedList, which happened to register
modes in non-canonical order - that was a test bug.

This patch drops the lookahead in Preformatted::connectTo, the
registerLineStartMarkers call in Listblock::preConnect, the
register/getLineStartMarkers methods on ModeRegistry, and the
three registry-API unit tests. testPreformattedList now
registers Listblock before Preformatted.

add GfmCode / GfmFile for fenced code blocks

GfmCode (backticks) emits the `code` handler instruction; GfmFile
(tildes) emits `file`. Column-0 fences only, no length pairing
between opener and closer, and unclosed fences stay literal —
matching DokuWiki's `<code>` tag convention. The info string accepts
DW's full attribute vocabulary (language, filename, [options])
through a new shared `Helpers::parseCodeAttributes` that `Code`
also uses, with `html` aliased to `html4strict` and `-` meaning "no
language".

Preformatted's indent threshold is now preference-gated: 2 spaces
in DW-preferred settings, 4 spaces in MD-preferred, matching GFM's
indented code block rule. A single tab is a trigger in both.

move handler methods into ParserMode classes and rename Handler

Each ParserMode class now implements handle() from ModeInterface,
containing the token handling logic that previously lived as individual
methods on Doku_Handler.

The Handler class (formerly Doku_Handler) is the single dispatch point:
Lexer passes tokens to Handler::handleToken() which routes to mode
objects, plugins, or returns false. The Lexer only tokenizes and
resolves mapHandler aliases.

Key changes:
- Add handle() to ModeInterface, implemented by all mode classes
- Move Doku_Handler to dokuwiki\Parsing\Handler namespace
- File extends Code (shared parsing via $type property)
- Quotes uses mapHandler() + Handler::getModeName() for sub-modes
- Media::parseMedia() replaces Doku_Handler_Parse_Media()
- Code::parseHighlightOptions() replaces parse_highlight_options()
- Per-parse state (footnote, doublequote) stays on Handler
- Deprecated wrappers kept for base/header/internallink/media
- Class alias and rector rules added for backward compatibility

decouple hardcoded mode names in Eol and Preformatted

Eol.php hardcoded ['listblock', 'table'] as modes to skip, and
Preformatted.php hardcoded [\*\-] as a negative lookahead for list
markers. Both embed knowledge that belongs to the respective block
modes, not to Eol/Preformatted. Adding a new block mode that handles
its own EOL or uses different line start markers would require editing
these unrelated files — a hidden coupling.

Listblock and Table now register themselves on ModeRegistry during
preConnect(). Eol queries getBlockEolModes() and Preformatted queries
getLineStartMarkers() to build its lookahead dynamically. Each mode
owns its own data, and new block modes can participate without touching
unrelated files.
